Work out the tip, the grand total, and how much each person owes when splitting the bill.
How the Tip Calculator works
The tip calculator multiplies your bill by the tip percentage, adds that tip to the bill, then divides the total by the number of people. Three short formulas do all the work:- Tip = Bill x (Tip% / 100)
- Total = Bill + Tip
- Per person = Total / Number of people
Each input is simple. Bill is the amount you choose to tip on - either the pre-tax subtotal (the customary base) or the after-tax total. Tip% is the gratuity rate, usually 15-20% for US table service. Number of people is how many ways you are splitting the check.
Here is exactly what the tool does internally, step by step:
- Reads your bill amount and treats it as the tip base.
- Converts the tip percentage to a decimal (20% becomes 0.20).
- Multiplies base x decimal to get the dollar tip.
- Adds the tip back to the bill to get the grand total.
- Divides the total by the head count to get each person's share.
- Optionally rounds the per-person amount up to a whole dollar so the cash everyone hands in still covers the check.
Edge cases it handles cleanly: a tip of 0% (the total just equals the bill, useful for a check-math-only split where gratuity was already paid); one person (per person equals the total); and uneven cents, where dividing by 3, 6, or 7 people leaves fractions of a cent - the tool rounds each share up so the collected money still covers what is owed instead of falling a penny short. You can also reverse it: if you want a clean round total, the tool backs into the exact tip percentage that gets you there. Unlike a plain percentage tool, everything here is framed around the one decision diners actually make at the table - how much to leave the server and how to divide it fairly.
]]>Example calculation
Below are three real-world tipping scenarios, each fully worked.Example 1 - Dinner for two, standard 20%. Your pre-tax bill is $86.40. Tip = $86.40 x 0.20 = $17.28. Total = $86.40 + $17.28 = $103.68. Split two ways: $103.68 / 2 = $51.84 each.
Example 2 - Group of five with auto-gratuity. A party of five gets an 18% auto-gratuity added by the restaurant. The food bill is $213.75. Tip = $213.75 x 0.18 = $38.48. Total = $213.75 + $38.48 = $252.23. Split five ways: $252.23 / 5 = $50.45 each. To make cash simple, round each share up to $51; five people contribute $255, which covers the $252.23 and leaves $2.77 toward the server.
Example 3 - Quick coffee run. Your bill is $12.50. At 15% the tip is $1.88 for a $14.38 total; at 20% the tip is $2.50 for a clean $15.00 total. On small tabs, jumping a few percent costs pennies but means a lot to a barista, so rounding up to a whole number is the easy move.
| Scenario | Bill | Tip % | Tip $ | Total | People | Per person |
|---|---|---|---|---|---|---|
| Dinner for two | $86.40 | 20% | $17.28 | $103.68 | 2 | $51.84 |
| Group + auto-grat | $213.75 | 18% | $38.48 | $252.23 | 5 | $50.45 |
| Coffee run | $12.50 | 20% | $2.50 | $15.00 | 1 | $15.00 |
Notice the pattern: the percentage is the same idea every time, but the dollar tip and the split change with the bill size and head count. The calculator does all three lines instantly so you are not doing mental math at the table while the server waits.
]]>Tips for using the Tip Calculator
- Tip on the pre-tax subtotal, not the after-tax total. On an $80 meal with 8% tax, tipping 20% on the $80 subtotal is $16.00, while tipping on the $86.40 total is $17.28 - a $1.28 gap every meal that adds up over a year. Both are acceptable; tipping on the subtotal is the technically correct baseline.
- Before adding your own tip, scan the bill for an existing auto-gratuity. Large parties (commonly 6 or more) are often charged 18-20% automatically, and the tip line is left blank on purpose. People routinely tip a second time on top of it.
- Use the 'double the tax' shortcut only where it works. In states with roughly 8-10% sales tax, doubling the tax lands near 16-20%. In low-tax or no-tax states it badly underestimates, so fall back to the calculator.
- For counter service and coffee, a flat $1-2 or rounding up to the next dollar is the norm rather than a strict percentage - 20% of a $4 latte is under a dollar, which feels stingy.
- Tip delivery drivers 15-20% with a roughly $5 minimum, and remember the delivery fee on the app usually does not go to the driver. Tip extra in bad weather or for a large, heavy order.
- For a haircut or color, 15-20% of the service price is standard, handed to the stylist directly; if multiple people helped (shampoo, color, cut), split a little to each.
- At hotels, tip housekeeping $2-5 per night left daily with a note (staff rotates), and bellhops $1-2 per bag. Leaving it all on checkout day can mean the wrong shift gets it.
- When splitting unevenly, allocate tax and tip in proportion to what each person ordered, not by dividing the grand total equally - the big eater should carry the bigger share of both.
- When traveling, research the destination first: in much of Japan, South Korea, and parts of Europe, tipping is minimal or unwelcome and a service charge may already be included. Over-tipping abroad is not generous, it can be confusing.
- Tip on the original price even when you used a coupon, Groupon, or comp. The server did the same work, so calculate the tip on what the bill would have been before the discount.
Pre-tax vs after-tax: which base should you tip on?
Tipping on the pre-tax subtotal is the correct baseline; tipping on the after-tax total is more generous but not required. Sales tax goes to the government, not the restaurant or server, so it has nothing to do with service. Etiquette experts treat the pre-tax subtotal as the proper base, but plenty of people tip on the grand total for simplicity. The difference is small per meal and meaningful over a year.
| Item | Tip on subtotal | Tip on total |
|---|---|---|
| Food subtotal | $80.00 | $80.00 |
| Sales tax (8%) | $6.40 | $6.40 |
| Tip base | $80.00 | $86.40 |
| Tip at 20% | $16.00 | $17.28 |
| Grand total paid | $102.40 | $103.68 |
The gap here is $1.28. If you eat out twice a week, tipping on the total instead of the subtotal costs roughly $133 more per year. If you want to keep your sales tax math separate from gratuity, run the bill through our sales tax calculator first, then tip on the food line only.
US tipping norms by service type
Table service is 15-20%; everything else has its own rule of thumb. Tipping in the US is not one number - it depends on who is serving you and how much labor was involved. Use this as a quick reference, then let the calculator do the dollars.
| Service | Typical tip |
|---|---|
| Sit-down restaurant | 15-20% of pre-tax bill |
| Bartender | $1-2 per drink, or 15-20% of the tab |
| Barista / counter | Round up or $1-2 (optional) |
| Food delivery | 15-20%, about $5 minimum |
| Hairdresser / barber | 15-20% of service |
| Taxi / rideshare | 10-15% |
| Hotel housekeeping | $2-5 per night |
| Hotel bellhop | $1-2 per bag |
The deeper your service, the closer you should be to the top of each range. For exceptional table service, 20-25% is a normal way to say thank you. Counter service is where people overthink it: dropping a dollar in the jar for a coffee is fine, and percentage math really only applies once a server is waiting on your table throughout a meal.
How auto-gratuity for large parties works
Auto-gratuity is a fixed service charge - usually 18-20% - that a restaurant adds automatically for large parties, and it replaces the tip you would normally choose. Restaurants do this because big tables take longer, tie up a server, and historically tipped less per head. The trigger is commonly a party of six or more, but the policy varies and should be printed on the menu.
Three things to watch: First, the charge is usually calculated on the pre-tax food total, the same base you would use anyway. Second, the printed tip line on the receipt is often left blank or shows the gratuity already filled in - if you write another number there, you may tip twice. Third, an auto-gratuity is a mandatory service charge, which is legally and tax-wise different from a voluntary tip; that is the restaurant's concern, not yours, but it explains why you cannot simply remove it for poor service the way you could lower a voluntary tip. If the service was genuinely bad, speak to a manager rather than crossing out the charge.
Splitting evenly vs splitting by item
Split evenly when everyone ordered roughly the same; split by item when one person had the steak and another had a salad. An even split is fastest: take the grand total and divide by the head count. Splitting by item is fairer but takes a minute - and the key trick most people miss is to allocate tax and tip in the same proportion as each person's food, not equally.
Say two diners share an $80 subtotal: Diner A ordered $60 of food, Diner B ordered $20. Tax is $6.40 and a 20% tip is $16.00. An even split is $51.20 each. A by-item split charges Diner A 75% of the tax and tip and Diner B 25%:
| Diner | Food | Tax share | Tip share | Owes |
|---|---|---|---|---|
| A | $60.00 | $4.80 | $12.00 | $76.80 |
| B | $20.00 | $1.60 | $4.00 | $25.60 |
| Even split | - | - | - | $51.20 each |
By item, Diner B pays $25.60 instead of $51.20 - a $25.60 saving versus the even split, while Diner A correctly carries the larger share. Allocating tax and tip by what each person actually ordered is the fair way to divide any shared restaurant check.
Common tipping mistakes
The most expensive tipping mistakes are double-tipping and tipping on the wrong base. Avoid these and you will tip fairly without overpaying.
- Tipping on top of an auto-gratuity. Always read the receipt before filling the tip line on a large-party check.
- Tipping on the after-tax total by accident. If you mean to tip 20% of the food, use the subtotal - the total includes tax you should not tip on.
- Counting the delivery fee as the tip. That fee usually goes to the platform, not the driver, so the driver still needs a separate tip.
- Dividing the grand total equally when shares were lopsided. The person with two cocktails should not be subsidized by the person who had water.
- Rounding the per-person share down. If you round each person's cash down, the collected total falls short and someone has to cover the gap.
- Tipping on a discounted bill instead of the full price. Comps and coupons reduce what you pay, not the work the server did - tip on the pre-discount amount.
How to calculate a tip by hand or in Excel
By hand, move the decimal one place left to get 10%, then scale: 20% is double that, 15% is 10% plus half of 10%. For a $86.40 bill, 10% is $8.64, so 20% is $17.28 and 15% is about $12.96. This mental shortcut gets you within pennies without any device.
In a spreadsheet, three formulas reproduce the whole tool. Put the bill in cell A1, the tip rate (as a decimal like 0.20) in A2, and the number of people in A3:
- Tip dollars: =A1*A2
- Grand total: =A1*(1+A2)
- Per person: =A1*(1+A2)/A3
- Round each share up to a whole dollar: =ROUNDUP(A1*(1+A2)/A3,0)
To reverse it - find the tip percentage that produces a round total - use =(TargetTotal-A1)/A1. For example, to make a $86.40 bill come to exactly $105.00, the formula returns about 0.215, or a 21.5% tip.
Tipping while traveling: is 20% normal everywhere?
No - the US is one of the most tip-heavy countries on earth, and over-tipping abroad can be a faux pas rather than a kindness. US servers are often paid a lower tipped minimum wage and rely on gratuities, which is why 15-20% is expected. Many other countries pay full wages and build service into the price.
General patterns when you travel: in much of Western Europe a small round-up (5-10%) is plenty, and a service charge labeled "service compris" or similar may already be on the bill. In Japan and South Korea, tipping is generally not practiced and can even cause confusion or offense. In Australia and New Zealand, tipping is occasional, not expected. Always check the bill for an included service charge before adding anything, and learn the local norm before you go. When you do tip abroad, tip in the local currency, and remember that a strong US habit of 20% can stand out for the wrong reasons.
Is your tip a good one? Benchmarks to check against
For US table service, 18% is the modern default, 15% is the floor for acceptable service, and 20%+ signals you were happy. Use these reference points to judge any tip at a glance.
| Tip % | What it signals | On a $100 bill |
|---|---|---|
| 10% | Below standard / poor service | $10 |
| 15% | Minimum acceptable | $15 |
| 18% | Standard / good service | $18 |
| 20% | Very good service | $20 |
| 22-25% | Exceptional service | $22-$25 |
A quick gut check: if your effective tip on the pre-tax subtotal lands between 18% and 20%, you are squarely in the normal US range and no one will think twice. If dining out is becoming a big slice of your monthly spending once tips are included, it is worth running the numbers in a savings calculator to see what redirecting even part of it could grow into.
Tip amounts by bill size and rate (US table service)
For US table service, the customary tip is 15-20% of the pre-tax subtotal, with 18-20% common for good service. The table below shows the recomputed tip in dollars at 15%, 18%, and 20% across common bill sizes, plus the grand total at 18% so you can see what you actually pay. Counter service, takeout pickup, and travel abroad usually call for less - use these figures only as a sit-down baseline.
| Pre-tax bill | Tip @ 15% | Tip @ 18% | Tip @ 20% | Total @ 18% |
|---|---|---|---|---|
| $20.00 | $3.00 | $3.60 | $4.00 | $23.60 |
| $50.00 | $7.50 | $9.00 | $10.00 | $59.00 |
| $75.00 | $11.25 | $13.50 | $15.00 | $88.50 |
| $100.00 | $15.00 | $18.00 | $20.00 | $118.00 |
| $150.00 | $22.50 | $27.00 | $30.00 | $177.00 |
Each tip equals bill x rate; the total column is bill + (bill x 18%). Run your own bill, rate, and party size in this tip calculator, and separate the gratuity from tax with the sales tax calculator.

Tip Calculator — frequently asked questions
- Standard US tip?
- 15–20% of the pre-tax bill for table service is common.
- Tip on tax?
- Customary practice is to tip on the pre-tax subtotal, though many tip on the total.
- Should I tip on tax?
- Customarily on the pre-tax amount, though many tip on the total.
- How much to tip for delivery?
- Often 10–20%, with a small minimum for short distances.
- On a $65 dinner, how much more is the tip if I tip on the total instead of the pre-tax subtotal?
- About $1.04 more, which is small. At 20% on a $65 pre-tax subtotal the tip is $13.00. If your state adds 8% sales tax ($5.20), the bill is $70.20, and 20% of that total is $14.04 - only <strong>$1.04 extra</strong>. Tipping on the pre-tax subtotal is the customary baseline, but the gap is minor, so many people just tip on the total. Our <a href="/sales-tax-calculator/">sales tax calculator</a> separates the two.
- How do I split a $48 bill three ways with an 18% tip?
- Each person pays about $18.88. An 18% tip on $48 is $8.64, making the total $56.64. Divide $56.64 by 3 people and each owes <strong>$18.88</strong> (the cents do not divide perfectly, so one person can cover the extra penny). Splitting after adding the tip keeps it fair since everyone shares the gratuity equally.
- How much should I tip a barista for a $5.75 coffee?
- Tipping a barista is optional, and $1 on a counter-service coffee is generous. For a quick $5.75 drink, dropping <strong>$1</strong> in the jar (about 17%) is a common, appreciated amount; loose change or nothing is also socially acceptable for simple counter service. Percentage tipping really applies to sit-down table service, not counter pickup. Reserve 15-20% for servers who wait on your table throughout a meal.
- A restaurant added 18% auto-gratuity on a $120 bill for 6 people - how much is that per person?
- It is $23.60 per person. An 18% auto-gratuity (added automatically for large parties) on a $120 bill is $21.60, bringing the total to $141.60. Split among 6 guests, that is <strong>$23.60 each</strong>. Because the tip is already included, you do not add another tip on top unless service was exceptional. Always check the receipt so you do not accidentally double-tip when gratuity is auto-applied.
- What is a fair tip for a $32 food delivery order?
- Around $5 to $6 is fair for a $32 delivery. A 15% tip is $4.80 and 20% is $6.40, so <strong>$5 to $6</strong> covers it for normal distance and weather. Many drivers and apps suggest a minimum of about $3 to $5 even on small orders, since delivery involves driving and gas. Tip more for long distances, bad weather, or a heavy order. The app's listed percentage is often calculated on the food subtotal, not fees.
- How much do I tip on a $45 haircut?
- Tip about $9, which is 20% of $45. The standard for hairdressers and barbers is 15-20%, so on a $45 cut that is <strong>$6.75 to $9.00</strong>. Many people round up to $9 or $10 for a clean cut and good conversation. If different people wash, color, and cut your hair, you can split the tip among them. Tip on the service price before any product purchases.
- For a $35 bill, how do I round the 20% tip to a clean total?
- Tip $7 for a clean $42 total. Exactly 20% of $35 is $7.00, which already lands on a round number ($35 + $7 = <strong>$42</strong>). When the math is messier, rounding the total up to the next dollar or five dollars is an easy, generous shortcut - for example bumping a $41.30 total to $42 or $45. Rounding up costs little and removes the need for change.
- What is the dollar difference between a 15%, 18%, and 20% tip on a $90 bill?
- The spread is $13.50 to $18.00, a difference of $4.50. On a $90 bill, 15% is $13.50, 18% is $16.20, and 20% is <strong>$18.00</strong>. So moving from a minimum 15% to a generous 20% adds just $4.50 total. That small gap is why many diners default to 20% for solid table service - the extra cost is minor and the goodwill is real.
- How much should I tip hotel housekeeping for a 3-night stay?
- Plan on roughly $3 to $5 per night, so about $15 for three nights. Leaving <strong>$15</strong> (at $5 per night) for housekeeping over a 3-night stay is a common US guideline; tip daily rather than once at the end, since cleaning staff often rotate. Leave the cash in a marked envelope or with a note so it is clearly a tip. Adjust up for messy rooms, extra requests, or upscale hotels.
- A $250 group dinner for 8 has a 20% included gratuity - what does each person owe?
- Each of the 8 people owes $37.50. A 20% included gratuity on $250 is $50.00, making the total $300.00. Divide $300 by 8 guests and each pays <strong>$37.50</strong>. Since the 20% is already built in, no one adds more on top. For large parties, restaurants commonly auto-add 18-20%, so confirm whether the printed total already includes it before splitting.
- How much do I tip on a $25 takeout order I pick up myself?
- Tipping on pickup takeout is optional; $0 to about $2.50 is typical. There is no table service, so many people tip nothing or round up. If staff packs a large or custom order, <strong>$2 to $3</strong> (around 10% of $25 is $2.50) is a kind gesture. Reserve full 15-20% tipping for sit-down meals and delivery, where the work is greater. A tip jar at the counter is always voluntary.
- How much do I tip a bartender per drink versus by percentage?
- Tip about $1 to $2 per drink, or 15-20% on a tab. For a single beer or simple pour, <strong>$1</strong> per drink is standard; for cocktails that take more work, $2 each is appropriate. If you run an open tab, tipping 15-20% of the final total works the same as table service. Per-drink tipping is handy when you pay round by round at a busy bar, where percentage math is awkward.
- Do I tip when traveling abroad the same way as in the US?
- No - tipping is far smaller or built-in across much of Europe and Asia, unlike the US 15-20% norm. In many countries a service charge is already included on the bill, and locals leave only small rounding or 5-10%. In places like Japan, tipping can even be seen as unnecessary. <strong>Check whether a service charge is listed</strong> before adding more, and research local norms; the US-style 18-20% expectation is unusually high by global standards.
- How do I figure each person's share when splitting a $72 bill by what they ordered?
- Add the same tip percentage to each person's items, then total their shares. If person A ordered $30 and person B ordered $42, apply 18% to each: A pays $30 plus $5.40 tip = <strong>$35.40</strong>, and B pays $42 plus $7.56 tip = $49.56. The two add up to $84.96, the same as an even split of the whole bill at 18%. Itemized splitting keeps it fair when orders differ in price while still sharing the tip proportionally.
